Abstract (en)

This invention enables a disk subsystem that employs the FC-AL connection to grasp the operation status of each disk drive, quickly locate a disk drive that has failed, and promptly carry out blocking processing. In a disk subsystem including plural drive enclosures (500) which store disk drives (540), and a disk controller (10) which controls transfer of data stored in the disk drives (540) between the drive enclosures (500) and a host computer. The drive enclosures (500) each comprise a backend switch (530) which is connected to the disk drives (540) and to the disk controller (10), the backend switch (530) comprises a status monitoring port (53b) through which operation status of switch ports of the backend switch (530) is outputted, and the disk controller (10) monitors a fault of the switch ports through the status monitoring port.
